Summary Possible clinical potential in reverting muscular block with sugammadex in anaesthesia and surgery Ugeskr Læger 2013;175(7):428-432 Neuromuscular blockers (NMBs) provide good conditions for endotracheal intubation and surgery. NMBs have been associated with higher morbidity and mortality, mainly due to postoperative residual neuromuscular block. This may become history with the advent of sugammadex - an antidote to the NMB rocuronium - which within 1-3 minutes neutralizes the effects of rocuronium. High-dose rocuronium is now an alternative to suxamethonium in acute or short procedures and in a situation, where ventilation/intubating cannot be performed, sugammadex can reverse the rocuronium blockade within minutes.
